Qianlong was the longest-lived emperor during China's feudal dynasty, succeeding to the throne at the age of 25, reigning for 60 years, and then serving as Emperor Taishang for three years and one month, actually ruling for nearly 64 years. Generally speaking, the concubines of the harem of the Longevity Emperor are indispensable, and the same is true of Qianlong, according to relevant statistics, there are at least 41 concubines in the Qianlong harem. So, which one is the one with the biggest age difference from Qianlong? She is the noble concubine.

Concubine Xun was born in the twenty-third year of Qianlong, that is to say, at the time of the birth of Ilgen Jueluo, Qianlong was already an old man who was nearly fifty years old (48 years old). From the point of view of birth, Ilgen Jue Luoshi belonged to the first class in the Qianlong harem, she came from Manchuria with a blue flag, and her father Guilin served as the governor of the local area, which became the key to her later favor.
At the beginning of the forty-first year of Qianlong, Ilgen Jue Luoshi participated in the Eight Flags Draft, and in this draft, the noble and beautiful Ilgen Jue Luoshi was favored by Qianlong, and then he was named a concubine, and as soon as he entered the palace, he was awarded the concubine position, which was not common in the history of the Qing Dynasty harem.
However, in the second year of Ilgen Jue Luo's entry into the palace, Qianlong's biological mother, Empress Chongqing (Empress Xiaoshengxian), died, so the canonization ceremony of Ilgen Jue Luo's concubine was temporarily shelved, and it was not until the forty-fourth year of Qianlong that he made up the canonization ceremony with Concubine Shun and Concubine Cheng.
In the first few years when Ilgen Jue Luoshi first entered the palace, Qianlong was very fond of her, often making her sleep, almost day and night, but he did not expect that this Ilgen Jue Luoshi's stomach has never moved, and it is estimated that it has something to do with Qianlong's age. Therefore, it did not take long for Qianlong to lose interest in Ilgen Jue Luoshi.
In the fifty-ninth year of Qianlong, when Qianlong was about to give up the throne, Qianlong enfeoffed the harem concubines, and Ilgen Jue Luoshi was thus promoted to concubine. However, what Irgen did not expect was that an oversight by an official of the Ministry of the Interior three years later took her life.
On September 28 of the second year of Jiaqing, which was the fortieth birthday of Ilgen Jue Luoshi, the officials of the Ministry of Internal Affairs sent the reward in advance, and when Qianlong learned of this matter, he was furious and severely reprimanded the officials of the Ministry of Internal Affairs, which also caused great psychological pressure on Ilgen Jueluoshi, and he died of illness in less than three months at the age of 40. Perhaps Qianlong felt that he had gone a little too far, so he ordered that Ilgen Jue Luoshi be buried with the etiquette of a noble concubine, which was a kind of compensation for her!
In addition, Qianlong ordered court painters to create a group of portraits for the harem concubines, called "Heart Writing Zhiping", which included a portrait of Ilgen Jue Luoshi, but this work was spread overseas in modern times and is now stored in the Borans Museum of Art in the United States, becoming a rare treasure similar to the treasure of the town hall.
